IMPROVEMENT IN GAS-HEATERS.

The Schedule referrd bo :In these Lettera Patent of the same.

To all whom it 'ma/y concern Beit known that I, WILLIA'M C. TROWBRIDGE,of the city, county, and State of New York, have invented a new andimproved Gas-Stove; and I do hereby declare that the following isa full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, referencel being had to theaccompanying drawings, forming part of this specification, in Which-Figure 1 represents a vertical section of my Aimproved stove.

Figure 2 is a'plan or top view of the same.

Similar letters of reference indicate corresponding parts.

This invention relates to certain improvements on that kind ofgas-stoves in which heated hydrocarbonliquids are consumed.

The invention consists, first, in a new arrangement of pipes forconducting the oil to the flame with an object of collecting impuritiesand sediments, before the oil or its vapors reach the' small orifice ofthe burner. frequently clogged by the impurities of the oil7 and theeifectiveness of the stove thereby impaired.

The invention also consists in constructing the stove of open work, forthe purpose of admitting air, to facilitate perfect combustion.

A, in thedrawing, represents the llame-cup of my improved stove. It ismade' of cast-iron, or other suitable material, of'suitable size andshape..` If made for a small stove, with a single opening in the topplate, I prefer to make it of circular form; but for larger stoves, itwill be correspondingly enlarged.

It is provided with a horizontal ilange, a, which projects from itsupper edge to the outside, and is perforated at its upper part.

The cup Ais supported on suitable legs, or standards, B B, which arefastened to its flange, a, or otherwise, as may be desired.

Up'on the flange is`placed a vertical plate, C, which supports the mainstove-plate D, the latter being, by means of bolts E E, secured to theflange a as shown.

The plate G is perforated at suitable intervals.

In the apparatus now in use, this orifice is' The stove-plate hassuitable apertures for cookingvessels.

F is a pipe conducting the hydrocarbon-liquid om the reservoir to thecup A.

lhe reservoir is higher than the stove.

The pipe, however, is conducted under the stove,

v*and then up, and throughan opening in the plate C,

into the stove, where it is turned down into thc cup and then bent upagain, its end carrying the burner b, as shown in iig. 1.

There is a plate, G, suspendedfrom the upper arm 0f the pipe F, directlyabove the burner, for the purpose of distributing the heat. Thehorizontal arm c of the pipe F, under the stove, serves to collect allsediments and impurities that are 'in the oil, and prevents them fromreaching the burner.

The oil, at the lstarting of a fire, escapes through the burner'andoverflows, in a very small quantity, into the cup A, where it is ignitedby applying a match.

The heat from this re causes the oil in the pipe to be converted intogas, and this gas will, when it issues from the burner, immediatelyignite, not falling into the cup.

When the lire has, for a short time, been in opera y tion, the gas alonewill burn, and there will be no flame on the bottom of the cup.

The perforations in the sides of the lcup A, andin the ring C, allowatmospheric air to the flame, and facilitate combustion.

I claim as new, and desire to secure by Letters Patent- 1. Carrying thepipe F under the stove, substantially as described, for thc purpose ofcollecting sedi-v
